Hello:
I would like to know what services are planned to be converged on the next
generation DSLAM boxes
from the service provider point of view. A servicve that was talked of was
the VPNs provisioned through
either ATM or IP/MPLS backbone networks. What would be the OSS support in
them? I would be interested
in the subscriber management models especially. Any known literature
available in the public domain?
I do understand that the majority of the current DSLAMs implement common
denominator function (that is to restrict their funcitonality at switching
or teminating ATM PVCs.) PPP and PPPoE,
designed to preserve dialup experience and capital investment of ISPs on
dial up infrastructure,
will be processed at the competitive or non-competitve ISP domains.
One view is http://www.potaroo.net/ispcolumn/2001-11-dsl.html
It appears that DSL systems are commonly built to conform to regulatory
requirements regarding competitive access as their primary objective, which
in turn often leads to less than optimal performance engineering in the
access network.
